As shown in fig. 2, 3, 4, 5, 6 and 7, when the device is used, the guide rod 7 can prop against the rotating plate 5 to enable the rotating plate 5 to intermittently rotate forwards and backwards through the left and right swinging of the guide rod 7, and in the process of rotating the rotating plate 5 forwards and backwards, the spring 12 in the connecting shell 2 props against the pressing plate 11 made of rubber materials to enable the pressing plate 11 and the rotating plate 5 to keep a close state, so that a sealing effect is achieved, the water flow from the water tank 1 can only flow out through the fixed pipe 3 in the process of intermittently opening or closing the rotating plate 5, the water flow can flow into the hole through the screen 1412 by externally connecting the fixed pipe 3, the function of intermittently injecting water into the hole is realized, the connecting rod 8 on the device can regularly clear the hole through the externally connecting water pump after water injection, the pressure spring 9 on one side is compressed when rotating, the compression spring 9 on the other side is stretched so as to reset the rotary plate 5 later, the larger the swing amplitude of the first circular ring 141 and the guide rod 7 of the device is, the more the single water inflow of the rotary plate 5 is, the single water inflow is regulated by changing the elongation of the electric push rod 146, the first anchor rod 6 on the device is used for limiting the guide rod 7, the guide rod 7 can only move in the hole on the upper half part of the first anchor rod 6, the stop block 10 ensures that the rotary plate 5 cannot rotate excessively to discharge water again after resetting, when the circular disc 145 performs circular motion, the drill rod 15 and the drill bit 16 also perform circular motion, the upper part of the drill rod 15 is connected with the circular disc 145 through a driving device, the circular drilling work is performed on the drill bit 16 under the condition of keeping the self structure unchanged, the reaming function is realized, the elongation of the electric push rod 146 can be regulated according to the requirement, thereby adjusting the size of the expansion hole;
as shown in fig. 5, 8, 9, 10, 11 and 12, in the process that the guide rod 7 intermittently dials the rotating plate 5, the guide rod 7 can reciprocate back and forth to make the guide rod 7 prop against the wire wheel 18, so that the wire wheel 18 intermittently pulls pull ropes 179 on the left side and the right side of the pile hole tamper 17, the pull ropes 179 drive the check rings 178, so that the check rings 178 intermittently rotate positively and negatively on the surface of the limit rings 174, the check rings 178 are connected with the compaction plate 177 and the limit block 1711 through the bolts 176, so that the device can drive the compaction plate 177 with equal angle distribution inside the check rings 178 to intermittently tamp the inner wall of the pile hole, the tension springs 1712 are used for resetting the compaction plate 177, the third anchor rods 171 and the ejector blocks 173 are used for fixing the connecting frame 172 and the limit rings 174, it is to be noted that the tamper is used for tamping a soil layer with loose hole walls during reaming, the soil layer which is caused by inserting anchor rods into soil at all positions on the device can be reinforced again, and the device needs to drill holes firstly when the hole wall is tamped, after the drilling depth is larger than the height of the tamping plate 177, the whole drilling machine is hoisted by a crane, then the pile hole tamping machine 17 is installed, the drilling machine is installed above the pile hole tamping machine 17, the tamping work of the inner wall of the pile hole is further carried out, in the drilling process of the drilling hole, the drill rod 15 and the drill bit 16 on the device adopt a conventional butt joint mode in pile foundation drilling, the drill bit extending function is realized through butt joint blocks at the head end and the tail end of the drill rod 15 and butt joint grooves which are matched with bolts (the butt joint mode can be seen in combination with fig. 1 and 2), the drilling work of the drill rod is realized, the tamping plate 177 on the device only performs the hole wall tamping work on the soil layer above in the drilling process, because the drilling depth can possibly be hundreds of meters, if the compaction plate 177 is extended into the ground, it is unstable, so the compaction plate 177 in this embodiment only compacts the upper layer of soil, and many of the lower layers are strata, and compaction is not required.
The above embodiments are only for illustrating the present invention, and are not limiting of the present invention. While the invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, and substitutions can be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
